6xx Area Codes Frequently Asked Questions
Common questions regarding numbering allocations, regional timezones, and caller verification.
What states and regions are served by 6xx area codes?
Area codes starting with digit 6 serve major metropolitan hubs and rural districts across Mississippi, Arizona, New Hampshire, South Dakota, Kentucky, and other jurisdictions.
How many area codes start with the digit 6?
Currently, there are 18 active North American Numbering Plan area codes assigned within the 600 through 699 numerical range.
Can I perform a reverse phone lookup for any 6xx phone number?
Yes. Enter the 10-digit number into our Reverse Phone Lookup tool to query carrier registries, line types (cellular, landline, VoIP), and subscriber names associated with 6xx prefixes.
Are calls from unfamiliar 6xx area codes safe to answer?
If you do not recognize a caller from a 6xx area code, check the number with a reverse phone lookup first. Robocallers frequently spoof local area codes to trick recipients into answering.
How do timezones work for area codes in the 600–699 range?
Area codes in the 6xx series span various American timezones (Eastern, Central, Mountain, Pacific, Alaska, and Hawaii). Inspect the specific area code listing above to determine its exact local timezone.
Can a cell phone have a 6xx area code even if the person moved?
Yes. Under federal mobile number portability regulations, wireless subscribers retain their original area codes even after relocating permanently across state lines.
What is the difference between landline and mobile numbers in 6xx area codes?
Landlines are tied to physical street addresses via copper or fiber, whereas cellular numbers are assigned to wireless SIMs. Reverse lookups identify line type and registered billing location.
Can telemarketers spoof 6xx area codes?
Yes. Malicious callers utilize VoIP dialers to spoof caller ID displays. A reverse lookup checks active carrier allocations to reveal if a number is an active wireless subscriber or virtual line.
Can I use records retrieved from 6xx phone lookups for background checks?
No. Reverse phone lookups are not consumer reports under the Fair Credit Reporting Act (15 U.S.C. § 1681) and cannot be used for tenant screening, hiring decisions, or credit evaluation.
How can a phone subscriber with a 6xx area code opt out of directories?
Subscribers can remove their records by submitting an opt-out request through Spokeo's removal page (spokeo.com/optout) or following our comprehensive Opt-Out guide.
